Apr\u00e8s 7 ans de suivi sur une parcelle d\u2019essai, de nouveaux r\u00e9sultats, satisfaisants, sont sortis des pr\u00e9l\u00e8vements et analyses sur l\u2019int\u00e9gration du compost issu des usines Trivalonne et Trivalandes.<\/strong><\/p>\n

Le 30 novembre, \u00e0 Grand\u2019Landes, Trivalis, la Chambre d\u2019Agriculture et Arvalis \u00e9taient r\u00e9unis dans un champ de bl\u00e9 appartenant \u00e0 un jeune agriculteur. Cette pr\u00e9sence sur champ, qui int\u00e8gre du compost depuis plusieurs ann\u00e9es, visait \u00e0 constater, \u00e0 mains nues, les b\u00e9n\u00e9fices du compost issu des ordures m\u00e9nag\u00e8res, sur la structure et la vie microbienne du sol. Pour la Chambre d\u2019Agriculture, \u00ab\u00a0le compost tout comme le fumier de bovin, am\u00e9liore la stabilit\u00e9 structurale du sol, contribue \u00e0 limiter l\u2019\u00e9rosion<\/em>, et augmente la capacit\u00e9 de r\u00e9tention en eau<\/em> \u00bb. Pour le jeune agriculteur, \u00ab\u00a0le compost est \u00e0 7 km, c\u2019est un atout pour s\u2019en procurer. En plus, il est propre<\/em>\u00a0\u00bb.<\/p>\n

L\u2019autre objectif de cette rencontre portait sur les r\u00e9sultats de l\u2019essai en cours sur des micros-parcelles dans le Sud Vend\u00e9e, \u00e0 Oulmes. L\u2019essai, suivi par la Chambre d\u2019Agriculture, est en place depuis 2014 sur 1 hectare o\u00f9 est compar\u00e9 l\u2019apport de compost \u00e0 l\u2019apport de fumier de bovin et \u00e0 aucun apport de mati\u00e8re organique. L\u2019essai vise \u00e0 mesurer les effets agronomiques, les risques sanitaires sol et plantes, les effets sur la structure du sol et les effets sur la vie biologique du sol.<\/p>\n

Le compost produit peu d\u2019effets sur l\u2019azote. Apr\u00e8s quatre int\u00e9grations au cours des 7 ans d\u2019essai, cadmium, mercure et chrome sont pr\u00e9sents dans le sol au m\u00eame niveau que le fumier de bovin. Les teneurs en cuivre et en zinc, de la modalit\u00e9 \u00ab\u00a0compost\u00a0\u00bb, d\u00e9passent celles de la modalit\u00e9 \u00ab fumier\u00a0\u00bb. Mais ce sont deux oligo-\u00e9l\u00e9ments dont les plantes ont besoin.<\/p>\n

Cet essai sur parcelle, d\u00e9but\u00e9 en 2014, prend fin en 2022. Des agriculteurs, non encore utilisateurs du compost Trivalis, \u00e9taient pr\u00e9sents \u00e0 Grand\u2019Landes. A eux et aux autres agriculteurs de France, Damien Grasset, pr\u00e9sident de Trivalis et de la FNCC, ravi d\u2019\u00eatre sur le terrain, leur d\u00e9clarait : \u00ab Nous avons besoin de vous pour d\u00e9fendre la fili\u00e8re contre l\u2019engrais chimique<\/em>\u00a0\u00bb.<\/p>\n
